Tekinoroji nyowani yekuchaja isina waya kubva kuChalmers University inogona kupa kusvika ku500kW yemagetsi nekurasikirwa isingasviki 2%.
Vanoongorora paChalmers University kuSweden vanoti vakagadzira michina yekuchaja isina waya inokwanisa kuchaja mabhatiri anosvika 500 kilowatts pasina kuabatanidza nechaja ine tambo. Vanoti michina mitsva yekuchaja yakwana uye yakagadzirira kugadzirwa. Tekinoroji iyi haizo shandiswe kubhadharisa mota dzinotakura vanhu, asi inogona kushandiswa mumaferi emagetsi, mabhazi, kana mota dzisina munhu dzinoshandiswa mumigodhi kana zvekurima kubhadharisa pasina kushandisa robhoti ruoko kana kubatanidza kune sosi yemagetsi.
Yujing Liu, Purofesa weMagetsi Injiniya muDhipatimendi reMagetsi Injiniya paChalmers University, anotarisisa nezve renewable simba shanduko uye magetsi ekufambisa masisitimu. "Marina inogona kuve nehurongwa hwakavakirwa mukati hwekuchaja chikepe pane dzimwe nzvimbo dzekumira kana vafambi vakwira nekuburuka mungarava. Otomatiki uye yakazvimirira zvachose yemamiriro ekunze nemhepo, iyo system inogona kubhadhariswa makumi matatu kusvika makumi mana pazuva. Marori emagetsi anoda kubhadharisa simba guru. tambo dzekuchaja dzinogona kukora uye kurema uye kunetsa kubata."
Liu akati kukurumidza kukura kwezvimwe zvinhu uye zvinhu mumakore achangopfuura kwakavhura musuwo wemikana mitsva yekuchaja. "Chinhu chakakosha ndechekuti isu tave neruzivo rwepamusoro-simba silicon carbide semiconductors, izvo zvinodaidzwa kuti SiC components. Panyaya yemagetsi emagetsi, vangove vari pamusika kwemakore mashoma. Vanotitendera kuti tishandise magetsi akakwira, tembiricha yakakwira uye ma frequency ekuchinja,” akadaro. Izvi zvakakosha nekuti kuwanda kweiyo magineti inodzikamisa simba rinogona kutamiswa pakati pemakoiri maviri ehukuru hwakapihwa.
"Yakapfuura isina waya yekuchaja masisitimu emotokari dzakashandiswa ma frequency akatenderedza 20kHz, senge oveni dzakajairika. Dzakave dzakakura uye kufambisa kwemagetsi kwaive kusashanda. Iye zvino tiri kushanda pamafrequency zvakapetwa kana. Ipapo induction yakaerekana yakwezva,” akatsanangura kudaro Liu. Akawedzera kuti timu yake yekutsvagisa inochengetedza hukama hwepedyo nevaviri vevanotungamira pasi rose vagadziri veSiC module, imwe kuUS uye imwe kuGermany.
"Navo, kukurumidza kusimukira kwezvigadzirwa kuchanangidzirwa kune yakakwirira mafungu, voltages nemhedzisiro. Makore maviri kana matatu oga oga, shanduro itsva dzichatangwa dzinoshivirira. Aya marudzi ezvikamu zvinhu zvakakosha, kune huwandu hwakasiyana hwekushandisa mumotokari dzemagetsi, kwete kungochaja inductive. " “.
Kumwe kubudirira kweruzivo rwemazuva ano kunosanganisira waya dzemhangura mumakoiri ayo anotumira nekugamuchira magineti anotenderera anoumba bhiriji chairo rekuyerera kwesimba pane gap remhepo. Chinangwa apa ndechekushandisa iyo yepamusoro-soro inokwanisika frequency. “Zvino haishande nemakoiri akakomberedzwa newaya yemhangura yenguva dzose. Izvi zvinokonzeresa kurasikirwa kukuru pakuwanda, ”akadaro Liu.
Pane kudaro, makoiri aya ave neakarukwa "tambo dzemhangura" dzakagadzirwa ne10,000 fiber fibers chete 70 kusvika 100 microns gobvu - anenge saizi yetambo yebvudzi remunhu. Izvo zvinodaidzwa kuti litz wire braids, inokodzera kukwira kwemhepo uye yakakwirira frequency, yakaonekwa zvakare munguva pfupi yapfuura. Muenzaniso wechitatu wetekinoroji nyowani inogonesa kuchaja isina waya ine simba imhando nyowani ye capacitor iyo inowedzera reactive simba rinodiwa necoil kugadzira yakasimba yakakwana magnetic field.
Liu akasimbisa kuti kuchaja mota dzemagetsi kunoda kuchinjika kwakawanda pakati peDC neAC, pamwe nepakati pemazinga akasiyana emagetsi. “Saka kana tichiti tawana 98 muzana kunyatsoshanda kubva kuDC pachiteshi chekuchaja kuenda kubhatiri, nhamba iyoyo hainei zvakanyanya kunze kwekunge wanyatsojeka pane zvauri kuyera. Asi iwe unogona kutaura zvakafanana. , Zvisinei nekuti unoshandisa Kurasikirwa kunoitika kungave neyakajairwa conductive kuchaja kana nekuchaja inductive. Kushanda zvakanaka kwataita ikozvino kunoreva kuti kurasikirwa mukuchaja inductive kunogona kunge kwakadzikira senge mu conductive charging system. Musiyano wacho muduku kwazvo zvokuti mukuita haukoshi, chinenge chikamu chimwe kana zviviri muzana.”
CleanTechnica vaverengi vanoda specs, saka izvi ndizvo zvatinoziva kubva kuElectrive. Chikwata chekutsvagisa chaChalmers chinoti tambo yayo yekuchaja isina waya inoshanda ne98 muzana uye inokwanisa kuendesa kusvika ku500kW yakananga ikozvino pamativi maviri emamita ine 15cm yemhepo gap pakati pepasi nepabhodhi pads. Izvi zvinoenderana nekurasikirwa kwegumi chete kW kana 2% yeiyo theoretical yakanyanya kuchaja simba.
Liu ane tarisiro nezve iyi nyowani isina waya yekuchaja tekinoroji. Semuenzaniso, haafungi kuti ichatsiva nzira yatinochaja nayo mota dzemagetsi. “Ini ndinotyaira motokari yemagetsi pachangu, uye handifungi kuti inductive charger ichaita mutsauko mune ramangwana. Ini ndinotyaira kuenda kumba, plug iyo mukati ... hapana dambudziko. " patambo. "Zvichida hazvifanirwe kupokana kuti tekinoroji pachayo inogadzikana. Asi zvinogona kuita kuti zvive nyore kuisa magetsi mumotokari huru, izvo zvinokwanisa kukurumidza kubuda kwezvinhu zvakaita sezvikepe zvinofambiswa nedhiziri,” vakadaro.
Kuchaja mota kwakasiyana kwazvo nekuchaja chikepe, ndege, chitima, kana tambo yemafuta. Mota zhinji dzakapakwa 95% yenguva. Michina yakawanda yebhizinesi iri kushanda nguva dzose uye haigone kumirira kuti ichajiwe. Liu anoona mabhenefiti ehunyanzvi hwekuchaja tekinoroji kune aya mamiriro ekutengesa. Hapana munhu anoda chaizvo kuchaja mota yemagetsi 500 kW mugaraji.
Chinangwa chechidzidzo ichi hachisi chekuchaja pasina waya pase pase, asi kuti tekinoroji inoenderera mberi sei nekuunza nzira nyowani, dzakachipa, uye dzakanyatsoshanda dzekuita zvinhu zvinogona kukurumidzira shanduko yemotokari yemagetsi. Funga nezvazvo senge zuva rePC, apo muchina wazvino uye mukuru wakapera usati watombosvika kumba kubva kuCircuit City. (Unovarangarira?) Nhasi, motokari dzemagetsi dziri kusangana nekuputika kwakafanana kwekugadzira. Chinhu chakanaka kudaro!
Steve anonyora nezve hukama pakati petekinoroji uye kusimba kubva kumba kwake kuFlorida kana chero kupi uko Simba rinomutora. Anozvitutumadza kuti “akamuka” uye haana basa kuti sei girazi rinotsemuka. Anodavira zvakataurwa naSocrates makore 3 000 apfuura: “Chakavanzika chekuchinja ndechokuisa simba rako rose pakugadzira zvitsva, kwete kurwisana nekare.”
